Azure ATP sensor : Could not create SSL/TLS secure channel
Microsoftaniketvpandey something is blocking proper TLS communication on localhost between the sensor process and the updater process.
EliOfek thanks for your advise, anything you would like to advise, it was working before?
I have checked TLS 1.2 enabled
- EliOfek
The TLS communication is on localhost :444, any chance there is a new FW rule that cause issues?
Some of the cases we know about were resolved by making sure these registry values are set to 0 (1 is not the default)
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL]
"DisableRenegoOnServer"=dword:00000001
"DisableRenegoOnClient"=dword:00000001
Was ADFS installed on this machine by any chance?
Hello,
I have the same problem on ADFS Sensor. It's Windows server 2019.
I didn't have problem on the Domain Controller just on ADFS.The service Update is running but not the service AATPSensor. It just starting again and again.
Can you help me?
